Percy holding Riptide: a sword made of celestial bronze.

Celestial Bronze is a powerful metal wielded by the gods and their demigod children.


Celestial bronze is mined by the Cyclopes from Mount Olympus. They shape the ore by tempering the metal in Mount Etna and cooling it in the River Lethe. The metal is deadly to creatures of the magical world. Unlike lesser mortals, demigods are also affected by it because of their blood. Artifacts of celestial bronze are known to emit a faint bronze glow. It disperses monsters into dust once a sword or weapon made up of Celestial bronze passes through them.

  • According to Reyna, Celestial Bronze is much rarer than Imperial Gold. However, this could simply be due to Camp Jupiter not having a large deposit (as they are on the opposite coast).
  • Celestial Bronze is one of three magical ores, the other two being Imperial Gold and Stygian Iron.
  • Except for Stygian Iron, Celestial Bronze and Imperial Gold are the only metals which turn monsters into dust.
  • "Celestial" means "from the sky" or "heavenly."

  • While Celestial Bronze is normally mined from Olympus, if Hephaestus is upset with his work, he throws pieces of Celestial Bronze into the mortal world.
  • As it is not silver, it cannot harm lycanthropes.
  • Unlike Imperial Gold, Celestial Bronze seems almost as abundent as iron to Greek Demigods, as not only their weapons made out of it, but it seems like almost everything the Greek Demigods make is made out of it, using it as a magical alternative to what other metals would normally be used for.
